    The construction industry has acknowledged that its current working practices are in need of substantial improvements in quality and efficiency and has identified that computer modelling techniques and the use of prefabricated components can help reduce times, costs, and minimise defects and problems of on-site construction. This paper describes a virtual environment to support the design and construction processes of buildings from prefabricated components and the simulation of their construction sequence according to a project schedule. The design environment can import a library of 3-D models of prefabricated modules that can be used to interactively design a building. Using Microsoft Project, the construction schedule of the designed building can be altered, with this information feeding back to the construction simulation environment. Within this environment the order of construction can be visualised using virtual machines. Novel aspects of the system are that it provides a single 3-D environment where the user can construct their design with minimal user interaction through automatic constraint recognition and view the real-time simulation of the construction process within the environment. This takes this area of research a step forward from other systems that only allow the planner to view the construction at certain stages, and do not provide an animated view of the construction process

    Interaction Design, which is essentially story-creating and telling, is at once both and ancient art and a new technology. Media have always effected the telling of stories and the creation of experiences. (Shedroff, N., 1994, p. 2) Advances with visual representations within broadcast design have been applied to areas such as weather simulations, sporting events, and historical reconstruction's. However, financial market information presentation is fairly uniform in television news broadcasting, showing little progression in pace with other news information catego­ries. While stock market news segments make limited use of supporting graphics, addi­ tional information that may assist the viewer is filtered out, effecting viewers interest, understanding and decision making process often associated with market related stories. Research to date has been limited to single visualisations. There has been little re­search into the use of multiple information views that are composed to support news presentations. People use many different information sources on a daily basis. News sources are used to stay informed about events, to some sources, viewer evaluation of informa­tion is a part of that process. News information and other data commodity sources are now more accessible, allowing designers to look at ways of transforming them into new or improved information services. This research explores the display of stock market information by looking at ap­propriate media delivery methods combined with Organic Information Interaction Design to enhance information relationships. Organic Design and Information Inter­action Design 1 principles are combined. This denotes a 'living' relationship between elements, incorporating hierarchy principles with enhanced information delivery and user experiences. Four themes are tied together through the use of a conceptual prototype. [FROM INTRO

    De/construction sites: Romans and the digital playground

    No full text
    The Roman world as attested to archaeologically and as interacted with today has its expression in a great many computational and other media. The place of visualisation within this has been paramount. This paper argues that the process of digitally constructing the Roman world and the exploration of the resultant models are useful methods for interpretation and influential factors in the creation of a popular Roman aesthetic. Furthermore, it suggests ways in which novel computational techniques enable the systematic deconstruction of such models, in turn re-purposing the many extant representations of Roman architecture and material culture

    Semiotic Analysis of Computer Visualization

    The purpose of this chapter is to discuss the semiotic approach to form theory of computer visualization. Such theory should be the foundation of design, development, and evaluations of visualization systems. The “direct” semiotic analysis of visualization is defined and the scheme of the analysis is considered. This analysis reveals “who is who” in the process of the visualization semiosis and helps in design and development of the real visualization systems. The analysis allows to describe the problems arising at developments of specialized systems in terms of the semiotics and showing how this analysis can serve as a tool for the visualization systems design. It is important to analyze the sign nature of the human‐computer interface and the visualization. Such conceptions as computer metaphor, metaphor action, and metaphor formula are defined. The properties of metaphors are analyzed with a view to possible usage of metaphors for specific applications. The properties are considered by the example of the hierarchical sequence of the natural Room‐Building‐City (Landscape) metaphors. Also the properties of the molecule metaphor are considered in the context of software visualization systems. In conclusion, some approaches to the theory of computer visualization are outlined

    Using access information in the dynamic visualisation of web sites

    Includes bibliographical references.Log file analysis provides a cost-effective means to detennine web site usage. However, current methods of displaying log analysis results tend to be limited in that they either contain no reference to a web site's structure, or else they portray this structure as a standard graph or tree. This dissertation presents a visual representation of web server log information, which addresses these limitations by incorporating log file data into a visualisation of a web site's layout. The devised visualisation utilizes properties unique to web sites in order to create a compromise between the clutter-prone network graph and the infonnation incomplete tree representations that have traditionally been used to depict web sites. As such, the visualisation emphasises typical web site features such as the home page, sub-sites and navigation bars. This approach pennitted the introduction of the concept of implying the presence of links without explicitly rendering them. This notion has many implications, not least of which is the reduction of cluttering. The visualisation combined several other techniques to address the issues of structure and data representation, data exploration, scalability and context maintenance. Assessment of the visualisation consisted of a heuristic evaluation by an expert from the web site usage industry, a test to detelmine the intuitiveness of the representation, and a series of user experiments. Results of the assessment were generally promising although a few areas of concern, such as the difficulty experienced by users in navigating the visualisation with a trackball, were identified. These issues should not prove to be too difficult to overcome however. The visualisation could thus be said to have successfully met the aim of developing a representation of web site usage infonnation that incorporates site structure and treats web sites as unique entities, thereby taking advantage of their particular characteristics. It is hoped such a visualisation will be of benefit to web site designers and administrators in analysing and ultimately improving their web sites

    Abstract:This research targeted complex abstract concepts in Computer Science and focused on bringing about the visualisation of such concepts using virtual world technologies. The research proposed the use of virtual world elements to support the understanding and learning of six computer science subjects having difficult theory concepts at the Higher Education level.The researcher decided to choose Higher Education as the platform for this research, due to the significant need to understand and learn complex abstract concepts of Computer Science at this level. The framework of the research is Higher Education within Further Education, which was chosen for its challenging nature with regards to students’ background and the level of additional support required for their success.The Second Life virtual world was selected and utilised to build purposely designed and scripted scenarios to empower the visualisation of complex theory concepts of the selected computer science subjects. These scenarios were embedded, in a predetermined order, within the curriculum delivery of a number of selected Computer Science modules from a Foundation Degree and a BSc (Hons) in Computing Programmes in a FE college in England. The research activities were carried out in two academic years, 2012/2013 and 2013/2014, in order to involve more students and obtain additional data to effectively, and more accurately, answer the research questions.The research aimed at identifying the extent to which using virtual world technologies to visualise difficult theory concepts in Computer Science subjects, might enhance students' learning and achievement. The research outcomes provided positive answers to the four research questions, which pursued the extent to which the visualisation of such concepts using Second life virtual world might, 1) facilitate students’ understanding of the complex abstract concepts in their HE Computer Science subjects, 2) increase students’ engagement in their HE Computer Science sessions, 3) enhance affective quality (to include elements such as appeal, enjoyment, interest and appreciation), and 4) improve student’s achievement (i.e. grades) in the targeted modules.In answer to these questions, the research outcomes showed that subject difficulty was reduced by 25% and around three quarters of students acknowledged enhanced learning in the virtual environment. Seventy percent of students acknowledged becoming more engaged in their study sessions that were carried out in virtual worlds, and more than three quarters of students acknowledged enhanced affective quality. Finally, around 85% of the modules covered by the research witnessed improved students’ achievement (i.e. higher grades).The researcher explained potential use, advantages and limitations of employing Second Life in Higher Education in general and HE Computer Science in particular, and provided recommendations to academic institutions that are interested in applying such virtual world technologies to overcome the challenges involved

    Virtual and Augmented Reality in Finance: State Visibility of Events and Risk

    Get PDF
    International audienceThe recent financial crisis and its aftermath motivate our re-thinking of the role of Information and Communication Technologies (ICT) as a driver for change in global finance and a critical factor for success and sustainability. We attribute the recent financial crisis that hit the global market, causing a drastic economic slowdown and recession, to a lack of state visibility of risk, inadequate response to events, and a slow dynamic system adaptation to events. There is evidence that ICT is not yet appropriately developed to create business value and business intelligence capable of counteracting devastating events. The aim of this chapter is to assess the potential of Virtual Reality and Augmented Reality (VR / AR) technologies in supporting the dynamics of global financial systems and in addressing the grand challenges posed by unexpected events and crises. We overview, firstly, in this chapter traditional AR/VR uses. Secondly, we describe early attempts to use 3D/ VR / AR technologies in Finance. Thirdly, we consider the case study of mediating the visibility of the financial state and we explore the various dimensions of the problem. Fourthly, we assess the potential of AR / VR technologies in raising the perception of the financial state (including financial risk). We conclude the chapter with a summary and a research agenda to develop technologies capable of increasing the perception of the financial state and risk and counteracting devastating events
